Do I have to say it? Its only worth what somebody is willing to pay for it. To get top dollar, you could put it at auction and hope that 2 or more folks are dying to have it. Honestly, I think all the resto parts and overall condition are going to carry more weight to a buyer than the fact it is a prototype. Personally, if I was looking to buy this game I think it worth about $1700 tops...but the inside better be as good as the outside to make that figure.
